STE NCILING-MACHINE Specication of Letters Patent.

Patented July 23, 1907.

Application filed October 23, 1906, Serial N o. 340,119. Renewed May 24, 1907. Serial No. 375,430.

To all whom it may concern:

Be it known that l, WILLIAM G. FUERTE, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented cercations of typewritten and autographic matter from paper stencils which have been waxed and from which portions of the wax have been removed by impact of a type-face, as in writing upon the sheet in a type-writer, or by traversing the waxedsurface of the sheet with the point of a stylus, or the like.

The present. invention, therefore, relates more particularly to a novel stenciling-machine in which the stencil issecured upon a hollow revolving cylinder carrying the usual ink-saturated blanket or pad and the stencil, the machine containing a novel and simply constructed equilibrating pressure-device which is regulatable to any desired degree of pressure of the usual pressure-roll against the stencil-bearing surface, and at the same time providing a uniform pressure while permitting a slight reciprocatory motion of the pressure-roll carrying-bearings, so as to allow the pressure-roll to readily accommodate itself to any inequalities that may exist in the paper as it passes over the pressure-roll.

The principal objectA of this invention is to produce a simple equilibrating pressure-device which is easily regulated and produces a uniform pressure so as to secure a perfect reprint of the writing or other like matter over the face of the sheet; and, furthermore, securing the delivery of the impression sheet in a perfect condition without the objectionable wrinkles or creases so often found with that class of stenciling machines now in use.

A further object of this invention is to provide a pressure-roller supporting means, comprising supports or bearings in which the roller is mounted, said supports or bearings being capable of reciprocatory motions vertically in a vertical plane passing through the longitudinal central axis of the stencil-carrying roll, so

that the line of rolling contact between the pressureroll and the stencil-carrying roll will lie inthis same vertical plane passing through the longitudinal central axes of ,these two rolls, and there can be no distortive rollingcontact or engagement between the parts, `as is liable with the rearwardly hinged or pivoted springlike bearing-arms or supports now generally employed, and which carry bearings in which the journals of the pressure-roll are mounted. In this manner a perfect contact will at all times result so that there will be no defective space between the parts to defeat the functions desired, by causing an uneven and broken continuity in the flow of the ink-supply through the openings formed in the stencil. Furthermore, the pressureroll can be released by throwing off the pressure without disturbing any of the parts of the pressure adjusting and regulating means, so that when the pressure-roll is again forced against the stencil-carrying cylinder or drum, it will bear against the lower surface of the cylinder or drum with the same pressure and in the same vertical plane passing through the central longitudinal axes of the two rolls.

Other objects of this invention not at this time more particularly mentioned will be clearly understood from the following detailed description.

With the various objects of this invention in view, ,the same consists, primarily, in the novel stenciling or reproducing machine hereinafter set forth; and, furthermore, this invention consists in the novel arrangements and combinations of parts, as well as in the details of the construction of the same, all of which will be hereinafter more fully described, and then finally embodied in the clauses of the claims which are appended to and which form an essential part of this specification.

The invention is clearly illustrated in the accompanying drawings, in which2 Figure 1 is a part front elevation and part longitudinal vertical section of a stenciling or reproducing machine embodying the principles of the present invention; and Fig. 2 is a side view of the machine, showing in connection therewith a worm-wheel and worm for adjustment of the shaft employed for setting the equilibrating devices, and a setting or holdingdevice for retaining the worm in its engagement with the wormwheel. Fig. 3 is a detail view of a portion of the framework of the machine and the worm-wheel and worm, and a pivoted setting or retaining device of a slightly modified construction. Fig. 4 is adetail transverse sectional representation of the lower portion of the framework of the machine, and a part of the pad and stencilcarrying roll or drum, said view illustrating in connection therewith the equilibrator shaft, a cam thereon,

and the spring-plate with which said cam is in engage-A as id Fig. 5, looking in the direction of the arrow :l: in said Fig. 5. Figs. 7 and 8 are two detail sectional representations of the lower portions of the frame-work of the machine and an elevation of the presser-roller and a portion of the stencil-bearing cylinder or drum, said views representing partly in elevation and partly in section two modified forms of pressure-equilibrating devices, both devices being made according to and embodying the principles ofthe present invention.

Similar characters of reference are employed in all of the above described views, to indicate corresponding parts.

Referring now to the several figures of the drawings, the reference-character 1 indicates the base of the frame or support of the apparatus, said bas'e or bed being provided at its ends with suitable standards 2 and 3, 'each *standard being provided upon its inner face with apair of inwardly extending vertical ribs or projections 4, forming a guide or way 5 for a box or bearing at each side of the frame of the apparatus. One of said standards, as 2, is provided with an upwardly extending member of element 6 carrying a bearing 7 in which is rotatably arranged the usual shank or spindle 8 provided with a finger-piece 9 at its outer end, and the inner Iend-portion of said shank or spindle being operatively connected with the central hub 10 of a single arm 1l carrying the usual drum or cylinder 12. The other standard 3 is provided upon its upper portion with the horns 13 carrying upon each end a roller 14. At the same time each horn is provided at its lower and centrally disposed portion with a suitably constructed bearing l5, see Fig. 1, in which is mounted a pin 16 upon which is arranged a third roller 17. This roller 17 serveslas a support for the end 18 of the drum or cylinder, and the upper rollers 14 prevent the cylinder from moving from side to side. The end 18 of the drum or cylinder is also made with a flange or open ring 19, the inner marginal edge-portion of said flange being movably tted against the outer face and along the inner marginal edge-portion of the previously mentioned horns 13, substantially as illustrated in Figs. l, 2, 7 and 8 of the drawings. The drum or cylinder 12 is thereby rotatively centered between the upper portions of the respective standards, the same being revolved by means of a handle 20, which extends from an Iarm or element 21 provided with clamping-devices 22 by means of which it is movably and adjustably clamped in any desired position upon the open ended portion of the drum or cylinder 12. That the said handle 20 may be folded vertically against the end of the drum or cylinder when the machine is not in use, the handle is preferably made in two parts 23 and 24, the part 23 being made with angular shoulders 25 and a narrow tongue 26 which extends into aslotted end 27 of the part 24, the parts being pivotally connected by means of a pin 28, and the angular shoulders 25 retaining the part 24 of the handle in its lowered and horizontal position, all of which is clearly indicated and will be fully understood from an inspection of Fig. 1 of the drawings. Each box or bearing hereinbefore mentioned, and movable vertically in said guides or ways 5, consists, preferably, of a block or plate 29 formed with a pair of upwardly extending ribs or members 30, the upper edge of each member being made concave, as at 3l, see Fig. 6, and having at their corner-portions perforated ears or lugs 32. Laterally extending pins 33 are arranged in cach 2 eLoa v pair of oppositely located ears or lugs, and upon each pin is a bearing-roller or trundle 34. In this manner, each standard 2 .and 3 is provided. with a vertically movable block carrying a pair of rollers or trundles 34, the same being sufficiently spaced apart to provide an anti-friction support for each journal 36 of the main shaft 35 of the pressure-roller to be presently more fully described. In order that there may be no lost motion longitudinally of the shaft 35, the journals 36 are of a reduced diameter, the shaft 35 being made with a shoulder 37 and each journal having an annular rib 3S, so as to form an annular groove of the proper width into which portions of the rollers fit and are in rolling contact with the journals 36, as Clearly illustrated in Figs. 1, 5, 6 and 7 of the drawings. The pressure-roller is usually a cylinder 39 made from a plastic material, such as rubber or the like, and the same is secured upon the shaft 35 in any suitable manner. Referring again to Fig. 4 of the drawings, it will be seen, that the main cylinder or. drum 12 is made with the usual ink-passages or perforations 40, and 41 is the ink-receiving pad or cushion, over which is arranged in the usual manner the stencil 42.

Coming now to the equilibrating device the same consists, essentially, of a shaft or rod.43 having its ends rotatably arranged in suitable bearings 44 formed upon the respective standards 2 and 3, each bearing being in alinement vertically with the journal-supporting box or bearing located within the guide or way directly above the bearing 44. Suitable means for turning or oscillating the shaft or rod 43 are provided, the same being hereinafter more fully described. Suitably secured upon the said shaft or rod 43 and centrally disposed b'etween the two standards 2 and 3 is a rearwardly extending lifting or raising member 45, the upper marginal edge of which is convexly curved, preferably as indicated at 46 in Fig. 4 of the drawings, and extends beneath and is movably disposed in supporting engagement with the lower face and central portion of an equilibrating spring-plate or bar 47. The end-portions 48 of this spring-plate curve upwardly, to provide the required spring-action, and at each extreme end is a preferably convexed end-member 49, each end-member 49 being provided with a slot'or an elongated opening 50 through which extends a screw 5l, the shank of which is'screwed into a screw-receiving socket 52 in the previously mentioned plate or block 29, substantially as illustrated in the several figures of the drawings. j In this manner the parts just described are operatively connected and any rotary movement vof the shaft or rod 43, causes the lifting or raising member to act upon the lower surface of said spring-plate or bar 47, to exert a lifting or releasing pressure upon the pressure-roller supporting boxes or bearings, as will be clearly evident, and in consequence thereof resulting in producing a uniform pressure of the pressure-roll directly against the extreme lower surface-portion of the main cylinder or drum 12, and the paper which has been inserted between the pressure-roller and said. drum or cylinder. That there may be no distortive movement of the spring-plate or bar and to allow for a slight oscillatory movement of said plate or bar, due to any inequalities of the paper, or of the stencil or ink-pad, and also to reduce to a minimum the frictional contact between the lifting or raising device 45 and the lower surface of the spring-plate or bar piece 59. Thus, it will be evident, that the engage- 47, a knife-edge or YV-shaped'marginal rib 53 may be formed upon the upper convex surface of said device 45, as clearly indicated in Figs. 1, 4 and 8 of the drawings, and the purposes oi which will be clearly evident from an inspection of said figures.

In lieu of connecting the end-members 49 of the springplate 47 to the slidable boxes or supporting bearings for the journals of the pressure-roller in the manner hereinabove described, the end-members of the spring-plate or bar 47 may be turned upwardly in a manner indicated in Fig. 8 ofthe drawings, the ends of said springplate or bar being provided with slotted or bifurcated bearing-portions 54 in which the journals 36 of the shaft 35 are rotatably arranged in the manner and as will be clearly understood from an inspection of said Fig. 8 of the drawings.

One means for manipulating the shaft or rod 43 and its lifting or raising device 44 is illustrated in Figs. 1, 2 and 3 of the drawings, an'd it consists, essentially, of a suitably constructed housing 55 in which is arranged a worm-wheel 56, the housing being loosely arranged upon the shaft 43 and said worm-wheel being fixed in position upon said shaft. The said housing is provided with a pair of forwardly extending bearing-portions 57 in which is rotatively arranged a worm 58 which is in engagement with the worm-wheel and has a {ingerment of said worm with the worm-wheel connects the housing with the shaft 43, whereby the housing may be used in. the manner of a handle or lever for quickly actuatifrg the shaft 43 and its lifting or raising device, and thereby quickly adjusting the equilibrating device, the parts being maintained in their adjusted positions by a device which is termed a kick-off This device consists, essentially, of a pair of arms 60 and 61, the upper arm 60 being pivotally connected by means of a pin 62 to a perforated lug or ear 63 of the housing 55 and the arm'61 being pivotally connected by means of a pin 64 to a projection 65 or other suitable part of the standard 3 of the machine-frame. That the two arms 60 and 61 may be retained in their rigid holding relation shown in Fig. 2 of the drawings, the arm 60 is made with a narrow tongue 66 which extends into the slotted end-portion of the arm 61 and is connected therewith by means of a pin 67, the arm 60 having angular edge-portions 68 and the arm 61 having angular edge-portions 69 which are brought in engagement with each other as shown to limit the movements of the parts. After this general adjustment has been made, very slight and ne adjustments may be made by turning the lfinger-piece of the worm, as will be understood, thus regulating the pressure o the pressure-roller to any desired degree. When it is desired to quickly release the equilibrator device, a slight -pressure in the direction of the arrow z in Fig. 2, against the two straightened-out arms 60 and 61 will cause the same to buckle, thus causing the housing 55 and the worm and worm-Wheel to partially rotate the shaft 43 in an opposite direction from that hereinabove described, thus releasing the raising device from the spring-plate or bar which allows the boxes inthe guides 5 to drop and thus removes the pressure of the pressure-roller from the bottom of the main cylinder or drum 12, as will be evident.

Another kick-off device is that shown in Fig. 3 of the drawings. This device consists simply of a lever or arm 70 pivoted at 7l to the projection 65, said lever or arm being provided with a finger-piece 72 for forcing the end 73 into or from its engagement with the lower surface of one of the bearing-portions 57 of the housing. A projection or rib 74 on said bearing-portion forms a suitable stop against which the end of the arm or lever 70 is brought to limit its movement. In lieu of either of the devices shown in said Figs. 1, 2 and 3 for actuating the shaft 43, an ordinary crank 75 may be employed, as clearly shown in Fig. -8 of the drawings.

In Fig. 7 of the drawings, I illustrated still another modified means for actuating the equilibrating mechanism. In this construction, instead of the spring-plate or bar 43, I employ a similarly formed bar 76 which is provided upon its lower face with a centrally dis-posed receiving socket or lug 77. Upon the base 1 is a perorated lug or ear 78, and upon a pin 79 is pivoted the eye-portion or end 8l of a kick-off-lever 80, said lever having its end-portion 82 extending from the side of the standard 3 and resting, normally, upon a stud or lug 84 of a latch-plate or arm S5. The lower end 83 of this latch-plate is pivoted by means of a pin 86 to the side of the standard 3 and has a handle or linger-piece 87 for actuating said latch-plate. The` said kick-off lever is provided also with a perforated ear or lug 88 carrying a pivotal pin 89 upon which is pivoted the slotted end of a socket 90. Loosely arranged within said socket 90 is the lower end of a stem 91 which is screw-threaded, as at 92, and has movably arranged upon said screw-threaded portion, an internally screwthreaded bevel-gear 93. The upper end-portion 94 of said stem 91 extends into the receiving socket or lug 77, as shown, and forms a support for the spring-bar or plate 76. In mesh with the bevel-gear 93 is a bevelgear 95, secured upon a rod or spindle 96, which is rotatively arranged in a bearing-portion 98 on a post or standard 97 and in a bearing 99 formed upon the standard or support 3. To turn the rod or spindle 96 in either direction, whereby the bevel-gears are correspondingly rotated and the stem 91 is moved up or down, according to the rotation, and to thereby bring the proper tension upon the spring-plate or bar 76, and the boxes which carry the pressure-roller, a suitable finger-piece, as 100, is secured upon the end of said rod or spindle 96. The operations of the various devices shown in said Fig. 7 for raising and lowering the springplate or bar 76 will be clearly understood from an inspection of said Fig. 7, the parts when in the positions shown always maintaining the operative engagement of the bevel-gears 93 and 95, but, when it is desired to quickly lower the equilibrating device, the pivoted arm or latch-plate is thrown back, and the lug or stud 84 is withdrawn from its supporting engagement with the lever 80. The latter therefore falls down upon the base 1, and the bevel-wheel 93 is disengaged from the bevel-wheel 95. With this downward movement the stem 91, and the equilibrating devices supported by said stem, also move in a downward direction, the boxes moving downwardly in the guides 5, and the pressure-roller is rapidly moved away from its operative contact with the main stencil-carrying drum or cylinder 12.

In a stenciling machine having a perforated inking cylinder to carry both an ink pad and a waxed paper stencil, the combination with a resilient roll to press the sheets against the stencil upon the cylinder, of guides for the ends of the roll, a yoke extending between said ends and loosely connected thereto, and means to bear upon said yoke midway of its ends to press the roll against the cylinder; said yoke constructed to yield where acted upon by said pressure device, to produce equilibrium in the pressure applied to the ends of the roll.

28. In a stenciling machine having a perforated inking cylinder to carry both an ink pad and a waxed paper stencil, the combination with a resilient roll to press the sheets against the stencil vupon the cylinder, of guideblocks for the ends of the roll, guide-ways for said blocks, a spring extending from one block to the other and loosely connected to both, and means to bear against said spring midway of its length to equalize the action of the ends of the spring upon the ends of the roll.

In testimony, that I 'claim the invention set forth above 1 have hereunto set my hand this 20th day of October, 1906.
